jibin sam philip

ReplyDeleteanother answer is -5

what about this logic?

23 1=24

21-2=19

now multiply the added/subtracted no.by 2

24 2=26

19-4=15

26 2=28

15-4=11

28 2=30

11-4=7

after doing it for 3times take the sum of the added/subtracted no.,i.e.(2 2 2=6)&&(4 4 4=12)

now add/subtract that with theprevious no.

30 6=36&&7-12=-5

Even I thought in this way and got an answer as -5. But its not correct. This will not grow the series in any good way...
